【摘要】：最近幾年嵌入式系統(tǒng)領(lǐng)域飛速發(fā)展，并逐漸演變?yōu)樵朴?jì)算和物聯(lián)網(wǎng)產(chǎn)業(yè)的支柱。作為系統(tǒng)的靈魂，尤其是大型復(fù)雜系統(tǒng)的嵌入式軟件開發(fā)，已經(jīng)成為嵌入式領(lǐng)域競爭的核心。然而，針對不同行業(yè)應(yīng)用的嵌入式開發(fā)工作遇到的困難和瓶頸也越來越明顯，嵌入式應(yīng)用也日趨多樣化，特別是在醫(yī)療、航空航天、汽車、電子、電力能源等行業(yè)，如何提供更高效、最佳實(shí)踐的服務(wù)和行業(yè)解決方案已成為每一個(gè)嵌入式軟件工程開發(fā)者和開發(fā)團(tuán)隊(duì)迫切需要解決的問題。 目前，基于構(gòu)件的軟件開發(fā)（Component-Based Software Development，CBSD）技術(shù)已經(jīng)成熟，該方法在傳統(tǒng)的軟件開發(fā)中業(yè)已普遍使用，其優(yōu)越性在于提高了軟件開發(fā)效率，，降低了軟件開發(fā)的費(fèi)用，保證了構(gòu)件的質(zhì)量和靈活性。因此將CBSD方法合理的引入嵌入式軟件開發(fā)中將能夠很好滿足嵌入式領(lǐng)域的多樣性特點(diǎn)以及對開發(fā)效率和軟件質(zhì)量的要求，以及提高嵌入式領(lǐng)域知識(shí)的重用性。目前的嵌入式構(gòu)件模型，要么缺乏通用性，要么缺乏可信保障，要么沒有對非功能屬性進(jìn)行表述，存在或多或少的問題。 論文在該研究背景下，通過分析CBSD技術(shù)，研究通用構(gòu)件模型，根據(jù)嵌入式軟件的物理性、實(shí)時(shí)性、資源受限性、領(lǐng)域性、多樣性以及與硬件密切相關(guān)等特點(diǎn)，結(jié)合當(dāng)前的相關(guān)研究，提出了一種嵌入式構(gòu)件模型DTESD構(gòu)件模型。 DTESD構(gòu)件模型針對當(dāng)前嵌入式構(gòu)件模型存在的相關(guān)缺陷做了分析和研究，提出了相關(guān)彌補(bǔ)方案。DTESD構(gòu)件不僅具有普通構(gòu)件的特點(diǎn)，還具有嵌入式構(gòu)件的專有特性，如物理性、多樣性等等。本文詳細(xì)描述了DTESD構(gòu)件模型的各個(gè)元素，設(shè)計(jì)了一種系統(tǒng)的元素描述語法；考慮到系統(tǒng)的多樣性特點(diǎn)，特別引入可變性原則；針對當(dāng)前嵌入式構(gòu)件模型缺乏非功能性描述的弊端以及構(gòu)件質(zhì)量保障的問題，專門做了可信研究，將其放置在構(gòu)件模型四大元素之一的屬性元素中做系統(tǒng)研究；為了更加利于分析，結(jié)合代數(shù)思想，提出了DTESD構(gòu)件的數(shù)學(xué)描述方式；最后結(jié)合基于DTESD模型做出的應(yīng)用實(shí)例，給出應(yīng)用分析結(jié)果，驗(yàn)證模型的有效性。
[Abstract]:In recent years, embedded systems have developed rapidly and become the backbone of cloud computing and the Internet of things industry. As the soul of the system, especially the embedded software development of large complex systems, it has become the core of the competition in the embedded field. However, the difficulties and bottlenecks encountered in the development of embedded applications in different industries are becoming more and more obvious, and embedded applications are becoming more and more diversified, especially in the medical, aerospace, automotive, electronics, power and energy industries. How to provide more efficient, best practice services and industry solutions has become an urgent problem for every embedded software engineering developer and development team. At present, the component-based software development (Component-Based Software Development,CBSD) technology is mature, and this method has been widely used in traditional software development. Its advantages lie in improving the efficiency of software development and reducing the cost of software development. The quality and flexibility of the components are guaranteed. Therefore, the reasonable introduction of CBSD method into embedded software development will be able to meet the diversity of the embedded field, development efficiency and software quality requirements, as well as improve the reuse of embedded domain knowledge. The current embedded component model is either lack of generality, credibility guarantee, or non-functional attribute representation, there are more or less problems. In this paper, by analyzing the CBSD technology, the general component model is studied. According to the characteristics of the embedded software, such as physical, real-time, resource limitation, domain, diversity and close relationship with hardware, etc. Based on the current research, an embedded component model (DTESD) is proposed. The DTESD component model analyzes and studies the defects existing in the current embedded component model, and puts forward the relevant compensation scheme. The DTESD component not only has the characteristics of common component, but also has the special characteristics of embedded component, such as physical property. Diversity, etc. In this paper, each element of DTESD component model is described in detail, and a systematic element description syntax is designed, considering the diversity of the system, the principle of variability is introduced. Aiming at the defects of non-functional description of embedded component model and the problem of component quality assurance, a trusted research is done, which is placed in the attribute element of one of the four elements of the component model. In order to be more convenient for analysis, the mathematical description method of DTESD component is put forward in combination with algebraic thought, and finally, the application analysis results based on DTESD model are given to verify the validity of the model.
